The locale gets its name from a spectacular battle in which the Temur devastated a swarm of attacking Mardu warriors. With charge after downhill charge, Surrak led his warriors against the invaders, leaving heaps of corpses so thick the hill seemed almost made of them. At the end of the battle, standing at the top, Surrak proclaimed that the Temur had climbed a staircase of their enemies' bones. The name stuck.
Outside of the winter months, the Temur sometimes assemble to hear the words of the Dragonclaw at the start of a war campaign. Word goes out through the Wide Whisper, and the various families gather at this hilltop. It is not a high peak, but its rounded top makes a good podium, and its relatively gentle slope allows easy climbing and standing or sitting as the clan leader speaks. It's also in a central location between the various family hunting grounds.
